Steps In Professional Window Cleaning
Wash With A Strip Applicator
The long cloth head of a strip applicator soaks up a lot of soapy water and knocks dirt loose without scratching the glass.
Wipe Clean With A Squeegee
Starting at the top left, pull the squeegee over the soapy pane in a reverse-S pattern (left-handers would start at the top right). At the end of each stroke, wipe the squeegee blade clean with a lint-free rag.
Dry Off Remaining Drips
Remove any water remaining on the edges of the glass with a damp, wrung-dry chamois, which soaks up wetness without leaving streaks. Dry the windowsill with a rag.
Scrubbing The Panes
A handheld sponge or hog-bristle brush works best on multi-pane windows. Using the same solution of a squirt of liquid soap in water, rub each pane from left to right, top to bottom, working the sponge edges or brush bristles into the corners to loosen dirt.
